The invention relates to a solid-liquid separation device for dredging mud in a ship lock approach channel, and belongs to the field of solid-liquid separation devices. The device comprises a separation box for the desilting machine and a feeding hopper arranged at the top of the separation box for the desilting machine. A coarse separation unit is arranged below the feeding hopper, and a fine separation unit is arranged at the bottom of the separation box for the dredging machine. The fine separation unit comprises a filter screen cylinder and two extrusion filter cylinders; semi-arc grooves are uniformly formed in the bottom of the separation box for the dredging machine; the filter screen cylinder is rotationally arranged in the semi-arc groove; the two extrusion filter cylinders are fixedly arranged on the two sides of the separation box for the dredging machine correspondingly and rotationally connected with the two ends of the filter screen cylinder correspondingly. A discharge hole is formed in one end, deviating from the filter screen cylinder, of the extrusion filter cylinder; a sealing unit is arranged at the discharge hole; the sealing unit is used for opening or closing the discharge hole; the filter screen cylinder is communicated with the two corresponding extrusion filter cylinders, and a working space is formed; a filter pressing unit is arranged in the working space in a sliding manner; the solid-liquid separation device has the technical effects of the solid-liquid separation device for ship lock approach channel dredging mud.

The utility model discloses a water area waste micro-plastic fiber separator, which comprises a separation tank, the bottom of the separation tank is respectively provided with a circulating spraying mechanism and a discharge port, the discharge port is communicated with the separation tank, the top of the separation tank is respectively provided with an installation groove and a feed port, the feed port is communicated with the separation tank, and the installation groove is communicated with the feed port. The two sides of the bottom of the separation tank are communicated with liquid outlets; according to the utility model, under the rotary matching of the conical filter plate and the annular baffle plate in the separation tank, fibers and impurities in waste micro-plastics are rotationally filtered on the surface of the conical filter plate, and under the blocking matching of the annular baffle plate to the conical filter plate, the impurities and the fibers are prevented from being vertically discharged together; and the opposite rotating structures of the two groups of brush plates on the outer side of the conical filter plate are utilized to promote the brush plates to scrape and brush plastic fibers and impurities on the surface of the conical filter plate, so that the separation rate of the fibers and the impurities is further enhanced, and the separation rate is improved.

The invention discloses a high-purity polyene fish oil extracting and distilling device, and relates to the technical field of distilling devices.The high-purity polyene fish oil extracting and distilling device comprises a distilling retort and a support for installing the distilling retort on the distilling retort, a motor is fixedly installed on the support, the output end of the motor rotationally penetrates through the outer wall of the support, and a rotating shaft is fixedly installed at the output end of the motor; the circumferential surface of the rotating shaft is in contact with the distillation retort, a fixed frame is fixedly mounted on the outer wall of the rotating shaft, the outer wall of the fixed frame is in contact with the distillation retort, and a distillation heater is mounted in the fixed frame; the high-purity polyene fish oil extracting and distilling device further comprises a turning mechanism mounted on the rotating shaft and an anti-sticking mechanism mounted on the rotating shaft, and during distillation and extraction, the rotating shaft drives the turning plate to turn over an extract, so that the extract is prevented from standing on an evaporation surface to form a liquid film boundary layer; the component separation rate in unit time is greatly improved, and the distillation time consumption is reduced.

This invention relates to the field of wastewater treatment technology, and in particular to a double-layer limiting plastic pin cleaning wastewater treatment tool, including a wastewater cylinder and a starting component for treating double-layer limiting plastic pin cleaning wastewater on a support block. Through the arrangement of the starting component, filtration component, and concentrating component, the bearing bar and bearing rod drive the scraper at the bottom of the lifting column to reciprocate and scrape along the curved surface of the irregular platform. The bearing plate continuously impacts and touches the inner wall of the cylinder, generating high-frequency vibration. The scraping and vibration work together to clean the plastic impurities adhering to the surface and pores of the irregular platform mesh in real time. Addressing the electrostatic adsorption effect generated by the friction between the release agent film on the surface of the plastic debris and the water flow, this dual action prevents plastic impurities from embedding and jamming the filter pores, avoiding the core problems of easy filter layer clogging, continuous decline in flow efficiency, and excessive fluctuations in suspended solids in the effluent. It maintains a stable effective flow area on the irregular platform filter surface and reduces the frequency of filter layer disassembly and replacement.
